Hello,
In Mageia it has been proposed that GRUB_ENABLE_CRYPTODISK=y be made the
default setting in /etc/default/grub for all installations, whether they
use encryption or not.

The discussion happens every now and then.

http://lists.gnu.org/archive/html/grub-devel/2013-12/msg00112.html

OK, thanks for the link.

In the case of Mageia the default installation puts everything required
by grub under /boot, so AFAICT this should not cause a problem.

... but it does.

I found time to do some testing, and adding it to the config on a system
with no encryption at all causes an error message:
error: device name required.

this seems to be triggered by this line which grub-mkconfig adds to
grub.cfg:

cryptomount -u


Does patch below help?
